Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

*The relative density D20/4 is the ratio between the measured density of the test substance at 20°C and the density of water at 4°C (= 0.99997 g/cm3). The relative density has no dimension.

 Check measurement: Density of degassed deionized water at 20°C: 0.99820 g/cm3

Reference value: 0.99820 + 0.00050 (20°C)

Conclusions:
A relative density value of 1.014 at 20°C was determined for the substance using a relevant test method. The result is considered to be reliable.

Description of key information

Relative density: 1.014 at 20°C (OECD 109)

Key value for chemical safety assessment

Relative density at 20C:
1.014

Additional information

A measured relative density value of 1.014 at 20°C was obtained using an oscillating densimeter in accordance with OECD Test Guideline 109 and in compliance with a known quality system (ISO 9001:2008). The result is considered to be reliable, and the study is selected as key study.


 


A predicted density value of 0.97 g/cm3 at 20°C was determined for the substance using a validated QSAR estimation method.


 


In available secondary sources to which reliability could not be assigned, density values of 1.02 g/cm3 at 20°C and 1.014 g/cm³ at 25°C were reported for the substance.
